HORSE HAY-RAKE.

SEECIFIGATION forming part of Letters Patent No. 683,445, dated October 1, 1901.

Application filed January 31, 1901. Serial No. 45,481. (No model.)

To all whom t may concern.:

Be it known that I, JOHN H. COX, acitizen of the United States, residing at Erie, in the county of Neosho and State of Kansas, have invented a new and useful Horse Hay-Rake, of which the following is a specification.

My invention is an improved horse hayrake; and it consists in the peculiar construction and combination of devices hereinafter fully set forth and claimed.

One object of my invention is to cect improvements in the means for rotating the rake-head to discharge the rake-teeth of their load and for locking the rake-head with the teeth in either operative or inoperative position.

Another object of my invention is to effect improvements in the construction of the raketeeth and in the combination therewith of the revoluble rake-head, which carries the raketeeth.

In the accompanying drawings, Figure 1 is a perspective View of a horse hay-rake constructed in accordance with my invention. Fig. 2 is an elevation of the same, partly in section. Fig. 3 is a detail perspective view showing the means for conveying power from the axle to the rake-head for revolving the latter and showing the means for locking the rake-head with the teeth thereof in either operative or inoperative position. Fig. 4 is a detail plan view showing the axle, the sprocketwheel thereon, the clutch member splined on the axle, the lock-bar, and the bell-crank lever connecting the latter with the splined clutch member. Fig. 5 is a detail perspective view of a section of the rake-head and of one of the rake-teeth, showing the construction of the latter and the manner in which the same is secured to the rake-head. Fig. 6 is a detail elevation, partly in section, showing the revoluble stop-disk having the brakefiange and the brake-spring bearing on said brake-ange.

The frame 1 may be of any suitable construction. As here shown, it comprises a front cross-bar 2, side bars 3, which extend rearward therefrom at the ends of said crossbar and are formed integrally therewith, and a cross-har., which is disposed at a suitable distance in rear of cross-bar 2 and has its ends secured on the side bars 8. Bearings 5 are secured to the side bars, and in said bearings is journaled 4a revoluble axle-shaft 6, on which are the wheels 7. Each of the said wheels is loose on said axle-shaft, and said wheels are secured on said axle-shaft by means of the usual pawl-and-ratchet mechanisms, which are not here shown, as their construction is well understood by those skilled in the mechanic arts, said pawl-andratchet mechanisms serving to lock the said wheels to the said axle-shaft and to permit the said wheels to slip and rotate idly on said axle-shaft when the rake is being turned. The frame is provided with the usual tongue 8.

A revoluble rake-head 9 is journaled in bearings l0 near the rear ends of the side bars 3. The said revoluble rake-head is provided with rake-teeth l1, which are more fully described hereinafter, and the said revoluble rake-head is provided near its center with a disk 12, which is fast thereon. A

sprocket-wheel 13 is also fast on the said revoluble rake-head and is located near the said disk.4 In one of the 'faces of disk 12 is an annular groove 14, which is provided at two points with offsets l5 16, which, in connection with a locking-bar, hereinafter described, serve to lock the revoluble rake-gear with its teeth in either operative or inoperative position.

A sprocket-wheel 17 is loose on the axleshaft 6, is connected to sprocket-wheel13 by an endless sprocket-chain 18, and isprovided on one side with a clutch member 19. A sleeve or collar 2O is splined on the axle-shaft, has an annular groove 21, and is further provided with a clutch member 22, which when in engagement with the clutch member 19 locks the sprocket-wheel 17 tothe axle-shaft and when out of engagement therewith permits said aXle-shaft to rotate independently of said sprocket-wheel 17.

A longitudinally-disposed bar 23 connects the cross-bars 2 4 and the revoluble rakehead, the latter being also journaled in a bearing 24, with which said bar is provided. A locking-bar 25 is movable longitudinally on the bar 23 and is retained in position thereon by a guide 26. The front end of the lockbar 25 is connected to afoot-lever 27, whereby said rod 25 may be operated, and the latter is provided at its rear end with an engag- IDO ing stud or pin 28, which rides in the annular groove 14 of disk 12 and is adapted to engage the offsets 15 16, which are disposed on opposite sides of said groove. A bell-crank lever 29 is fulcrumed to the bar 23, is connected to the lock-bar 25 and operated therepin 28'of rod 25 moves said stud or pin against an offset 15a, and thereby locks the revoluble rake-head against further rotation and disposes the rake-teeth in operative position.

When it is desired to lock the rake-teeth in inoperative position, the rod 25 is moved rearward by the lever 2-7, while the rake-head is being rotated and caused to engage the offset 16 'in the disk 12. It will beunderstood that when the stud or pin of rod 25 is in engage-k ment either with the oifset 15a or offset 16 the sleeve on the axle-shaft is unclutched from the sprocket-wheel 17, and hence power is not conveyed from the axle-shaft to the revoluble rake-head.

which comprises two members 32 33, hinged together at one end, as at 34, adapted to en gage said revoluble rake-head and said axlef shaft'and provided with hooks orother suit-i able devices 35 for securing them together.

the cross-bar 4 of the frame, as shown.

In order to clear the rake-teeth of any hay"y which may adhere thereto when the ra'ke.v

head is rotated in order to discharge a load in the formation of a windrow, I provide cleaning-bars 37,which have their front ends h secured to the frame 1 and which extend over and project rearwardly from the revoluble rake-head and are disposed at appropriatel distances apart and between the rake-teeth.

Each rake-tooth 11 is bent reversely at its` u-p'per end, as at 38, then laterally at right` angles, as -at 39, and then outwardly at right angles, as at 40, Vthe reversely-bent portion 38 and terminal portion 40 'being ,parallel with each other and passed through openings in the revoluble rake-head, as shown, andsaid terminal portion 40 is screw-threaded and provided with a nut 41 to secure the tooth -to the rakehead.

the-openings in the rake-head and which are Any other suitableA securing means may be employed instead.

substantially parallel eectually prevent the rake-teeth from turning in the rake-head.

On one side of the disk 12 is a segmentshaped brake-flange 42, which is engaged by a brake-spring 43 at the rear end of the bar 23 while the rake-head is being revolved on the descent of the rake-teeth to retard the descent of the latter, and hence avoid the jarring or jerking of the rake-head which might otherwise result.

Having thus described my invention, I claim- 1. In a horse hay-rake, the combination o-f a revoluble rake-head, a disk revoluble therewith, said disk having an annular groove on one side, a notch 1'6 communicating with said groove and offsets 15, 15a on opposite sides of said groove, a revoluble power element, a clutch to throwthe same into and out of gear, connections between said revoluble power element and said revoluble rakehead, to rotate the latter, a longitudinallymovable rod having `a stud or pin in the groove of said disk to engage `said notchand offsets, and a connection between `said rod and said clutch, whereby the latter is operated by the former, substantially as described.

2. In a horse hay-rake, the combination of a revoluble power-shaft, a revoluble power element loose thereon, a clutch to lock said power element to said shaft, a revoluble rake- I yhouse the operative connections hereinbefore described Abetween the axle-shaft and the vrevoluble rake head by a casing 31,

head connected to and rotated bysaid power element, a stop-disk on said rake-head, alongitudinally-movable stop-rod to engage said stop-disk, a brake element carried by said rod, and coacti'ng with said stop-disk to retard the descent of the rake-teeth as therakehead revolves, and a connection between the Y said stop-rod and said clutch, substantially as The seat 36 for the driver is supported by described.
